MPG, running costs & CO2 Rating

4.0 out of 5

While the Peugeot 508 SW is likely to be driven mostly by those running one as a company car, it’s an excellent family estate too. It suits both types of buyers, thanks in part to a range of efficient petrol, diesel and plug-in hybrid engines.

Peugeot 508 SW MPG & CO2

Almost every engine in the 508 SW is affordable to run but the 1.5-litre BlueHDi is likely to be especially popular in this class. With emissions from 124g/km of CO2, it has a reasonable BiK rating, keeping costs down for company-car drivers. Speccing the six-speed manual gearbox means it can return up to 63.6mpg, while the eight-speed automatic version gets almost the same figure. Step up to the 2.0-litre BlueHDi engine and the automatic is standard; fuel consumption drops to a maximum of 52.9mpg but it offers the same BiK rating because this engine meets the latest emissions standards and isn’t subject to an extra 4% in company-car tax.

The 1.6-litre PureTech petrol models will return up to 44 or 42.2mpg, and both also come with an auto as standard. These will work out quite expensive for business users, but should be popular with private buyers who don’t cover a huge number of miles.

In 2020, Peugeot introduced a plug-in hybrid version of the 508 SW that’s said to manage up to 235.4mpg and 39 miles of electric-only running when the battery’s fully charged. Charging from an optional 7.4kW wallbox takes an hour and 45 minutes, while using a standard three-pin socket will take over seven hours to fully recharge. Despite a high initial price, it’s the best choice for business users, as its BiK rating is just 10%.

Road tax costs £150 a year (£140 for the hybrid) but it's also quite possible to spend over £40,000, in which case a £325 surcharge is added in the first five renewal years.

Insurance groups

Insurance groups for the 508 SW shouldn't be any higher than the hatchback, but they do look high next to the Skoda Superb Estate. For instance, the entry-level diesel Peugeot starts in group 22, while the Superb Estate diesel starts from group 14. A range-topping petrol 508 SW GT finds itself in group 34 out of 50.

Servicing

The 508 SW requires annual servicing and Peugeot offers maintenance packages that can be covered monthly to help spread the cost. These can last for up to five years and cost around £15 a month.

Warranty

Peugeots come with a three-year unlimited mileage warranty that's competitive with brands like Skoda and Volkswagen but shorter than the five- and seven-year cover offered by Toyota, Hyundai and Kia. New Peugeots also benefit from Peugeot's roadside assistance, covering the owner and anyone driving the car with their permission.
